Locus: 16S rRNA, chloroplast genome
Locus: 23S rRNA, chloroplast genome
Source: Isolated at Duke from a spontaneous biparental zygote in a cross of GB-140 (nr-u-2-1 spr-u-1-H-4 sr-u-2-60) to CC-67 (er-u-37).
Comment: Used in chloroplast mapping crosses.
Caution! This is NOT the same thing as "wild-type strain 137C". If that's what you're looking for, try CC-124 and CC-125.
